1. i had accidentally gotten a bit of glue on my resin coaster, so I used some alcohol pads to get it off. In the process, I think I rubbed the opposite side of the coaster too hard on the table, and there is a matte spot now. I think it essentially got sanded off on the bottom by the motion of wiping on the top. I used the casting craft sealer spray to correct this (is this the right thing to do?) and even though I used thin layers, it ended up matte and rough. Can i recoat with resin on top of this sealer spray layer?
2. I made another coaster with a flower embedded and i didn’t realize that part of the petal was too “tall” and sticks out of the resin. the coaster mold is very shallow. how might I recoat so that every part of the flower remains below the surface of the resin? would I have to buy another mold? thank you!
